Abstract
A method of production of an ether compound from an acetal compound or a ketal compound which is excellent in conversion and selectivity and does not cause corrosion of apparatuses and a novel useful polyvinyl ether compound as lubricating oil for compression-type refrigerators, electric insulation oil and the like are disclosed. The method of production of the present invention comprises reaction of an acetal compound or a ketal compound with hydrogen in the presence of a solid catalyst having acidic property and hydrogenation ability to produce the corresponding ether compound.
Claims3
A method of production of an ether compound expressed by the general formula (II):
- ##STR19## or by the general formula (III):
- ##STR20## wherein R.sup.1 and R.sup.2 are a hydrocarbon group or a hydrocarbon group containing ether oxygens in the main chain, in the side chain or in the both of them, respectively, and may be the same or different from each other and R.sup.3, R.sup.4 and R.sup.5 are a hydrogen atom, a hydrocarbon group or a hydrocarbon group containing ether oxygens in the main chain, in the side chain or in the both of them, respectively, and may be the same or different from each other, which comprises bringing an acetal compound or a ketal compound expressed by the formula (I):
- ##STR21## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are the same as those in the general formulae (II) and (III), into the reaction at a temperature of 10.degree.-250.degree. C. with hydrogen at a pressure of 1-200 kg/cm.sup.2 in the presence of solid catalyst consisting of a combination of a hydrogenation catalyst and a solid acid catalyst.
